personal computers have become smaller yet increasingly more powerful today many daily

Early activities involve mobile communication and computer access both in and outside the home.

For some inventors, the next step is to integrate computers into accessories or into smart clothing, thus creating wearable computers.

Martin Kelly reports.

The concept of wearable computers is hardly innovative.

Early attempts at manufacturing them produced clumsy results.

The wearer had to wrap himself in wires

or strap a strange -looking device to his forehead and carry a backpack of computer equipment.

The technology didn't sell because in today's world, appearance is everything.

However, today's wearable computers may provide the solution.

Professor Tanya Carter is here to tell us more.

Wearable technology is evolving so fast that it has become not only extremely convenient, but a fashion statement too. For example,

handheld computers have been miniaturized enough to be strapped to the wrist like a watch not much larger than the average chronometer.

Though limited in applications, it is only a matter of time before the watch has full computing capacity.

This could eliminate the need to carry a laptop.

And rather than attaching all kinds of objects to a jacket, researchers are creating state -of -the -art textiles with electronics built in.

One such textile is composed of small patches of fabric into which minuscule computer chips have been embedded.

These patches are assembled with Velcro that conducts electricity to create a purse similar in appearance to an ordinary leather purse.

This purse provides you with information, such as the latest weather forecast.

It can also keep track of your wallet via a minute radio signaling chip attached to the wallet.

Sensors integrated into the purse's fabric transmit a message to alert you if the wallet is not inside.

This purse even allows you to upload your favorite music onto your music player, which, incidentally, could soon be inside your scarf.

I understand that scientists are creating accessories, but there are other innovations in the field of computer -integrated clothing, right?

What kind of initiatives are underway to adapt wearable computers for use in fields like health and emergency services?

Well, as monitors, wearable computers have many applications.

For example, a smart armband registers data about the wearer's physical condition.

It can help people lose weight by telling them how many calories they're burning at any given time during exercise.

Doctors could also use it to monitor the well -being of the elderly and infants, too.

One ingenious adaptation is a shirt made of a special fabric that has the capacity to analyze the wearer's heart rate,

respiration, and other key health indicators.

For example, it is being used today in medical research to examine the effectiveness of certain new heart treatments.

And since it can measure stress levels and body heat,

it could be used to monitor firefighters at a blaze or to allow a mother to check on her asthmatic child.

Another wearable item

that has proved remarkably helpful to runners who want to keep

fit is a sensor embedded into the sole of their running shoes.

The sensor relays information about the speed

and the distance you've covered to your iPod

and can change the music track to another song with a faster or slower tempo, thus encouraging you to accelerate your pace or reduce your speed.

The sensor is invisible and the earphones are the same as the ones on a regular iPod.

So fashion -wise, the wearer would not feel conspicuous.

Obviously, as technology advances, so will the wearable computer.

Ultimately, it could be a smart assistant that goes wherever we go, registering and analyzing data about us and our environment.

この動画での練習方法

まず声を出さずに動画を最後まで聞き、知らない単語をメモします。
通常の速度で一文ずつシャドーイングし、話し手のリズムに合うまで繰り返します。
自分の声を録音して元の音声と比べます。sensor, wallet, purseなどの単語に特に注意しましょう。

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
